Ya we did the same and my male duck did the funniest thing ever ok so my little brother is scared of them so he was sitting on the ground with some watermelon they came up to see what he had and he jumped up and the piece was 4 to 6 inches long anyway the biggest male grabbed it and shoved it down his throat and we thought we would choke but his throat expanded and u cpuld see it go down to his crop lol we laughed the entire time
